The Kinesis Freestyle has a mechanical version (https://amzn.to/2Emhout). I'm typing on it right now. I wonder how the author would have assessed the Kinesis if he had tried the mechanical version.
Quite a big increase in price for the mechanical part. The kinesis is a good split starter board, or for office drones.
There is a substantial difference in price, although the mechanical Kinesis costs less than what I paid for the regular Kinesis several years ago (prices have come down quite a bit). More importantly, years ago when I tried the regular Kinesis the mushy keys were unacceptable. It takes a fair amount of time/practice to acclimate to a split keyboard and I wasn't willing to do that for a non-mechanical keyboard; the mechanical version removes that obstacle.
